En el presente trabajo se ha realizado un estudio de la modificación de las propiedades mecánicas de la aleación de aluminio AA6060 F, al ser deformada mediante deformación plástica severa empleando el proceso de extrusión ... -
Analysis of fatigue and wear behaviour in ultrafine grained connecting rods
Over the last few years there has been an increasing interest in the study and development of processes that make it possible to obtain ultra-fine grained materials. Although there exists a large number of published works ... -
Analysis on the manufacturing of an AA5083 straight blade previously ECAE processed
Over these past few years, there have been a large number of technical papers published related to the problem of improving the mechanical properties of materials obtained through severe plastic deformation. Nevertheless, ... -
Analytical modelling of energy density and optimization of the EDM machining parameters of Inconel 600
In this present research work, a new modelling of energy density in EDM (Electrical Discharge Machining) is proposed. Energy density can be defined as the amount of energy needed to get a unit volume of material removed, ... -
Design and mechanical properties analysis of AA5083 ultrafine grained cams
This present research work deals with the development of ultrafine grained cams obtained from previously ECAP (Equal Channel Angular Pressing)-processed material and manufactured by isothermal forging. The design and the ... -
Design, optimization, and mechanical property analysis of a submicrometric aluminium alloy connecting rod
Ultrafine grained materials have a great deal of both scientific and technological interest because they allow outstanding properties to be obtained. An improvement in the mechanical strength and in the ductility and a ... -
Design, simulation and manufacturing of a connecting rod from ultra-fine grained material and isothermal forging
In this research work, a study on the mechanical properties of isothermal forging for connecting rods is made from previously ECAP (Equal Channel Angular Pressing)-processed AA1050 and AA5083 aluminium alloys. This severe ... -
Development of nanostructured AA3103 by equal channel angular pressing and thermal treatments
This work presents a study related to the achievement of a nanometric structure in AA3103, employing severe plastic deformation processes (SPD), in this case equal channel angular pressing (ECAP). The changes in the ... -
Experimental modelling of critical damage obtained in Al-Mg and Al-Mn alloys for both annealed state and previously deformed by ECAP
Assessing the damage produced in plastic deformation processes permits the optimum manner to shape a material that could avoid any cracks from appearing. In this present research work, the absolute critical damage in ... -
Manufacturing of nanostructured rings from previously ECAE-processed AA5083 alloy by isothermal forging
The manufacturing of a functional hollow mechanical element or ring of the AA5083 alloy previously equal channel angular extrusion (ECAE) processed, which presents a submicrometric microstructure, is dealt with. For this ... -
Mechanical properties analysis of an Al-Mg alloy connecting rod with submicrometric structure
Over these last few years, there has been a growing interest in developing mechanical components from submicrometric materials due to the significant improvement that these materials present compared to their original ... -
A proposal of a constitutive description for aluminium alloys in both cold and hot working
The most important difficulties when the behaviour of a part that is subjected to external mechanical forces is simulated deal with the determination of both the material thermo-mechanical properties and its boundary ... -
